Reminder from the devguide: A branch preparing for an RC release can only have bugfixes applied that have been reviewed by other core team members. Generally, these issues must be severe enough (for example, crashes) that they deserve fixing before the final release.

The absence of an immutable dict counterpart has been a long-standing gap in Python and has been requested for a long time in different forms. We agree this is a clear net positive for the language. We are accepting this PEP with the following modifications: Performance should not be framed as a goal or motivation. The value of frozendict is in its immutability semantics, not i
